MACHINE FOR FORMING OUTTURNED SHOE-UPPER-S.

To all whom it may concern:

.Be it known that I, WVILLIAM J. YOUNG, of Lynn, in the county of Essexand State of Massachusetts, have invented certain new andusefulImprovements in Machines for Forming Outturned Shoe-Uppers, of which thefollowing is a specification.

This invention relates to a machine for molding shoe uppers, especiallythe heel parts of the'same, with the edge which is attached to the bootor shoe sole turned outwardly. Heretofore in making shoes in which thesole is attached to the upper by outward flanges on the upper, oroutturned uppers, it has been the'practioe to turn-out the edges of theupper, by which the attaoh- .ing flanges are formed, by hand.

Accordingly my invention has for its objecttoprovide a' machine capableof performing the work hitherto done by hand, that "is, of forming bootand. shoe uppers with outwardly turned flanges'for attachmentto the soleof a boot or shoe.

The invention consists in the instrumen- ,talities constructed, arrangedand operating Fig. '2 represents a perspective view of a shoe upperhaving an outwardly turned edge at the rear or counter portion thereof,the same being the product of this machine. Fig. 3 represents alongitudinal section of themachine, showing the parts in the positionthey occupy'when a counter is operated upon. Fig. 4 representsacross-section of the counter mold and flange former,taken on lineH ofFig. 3. Fig. 5 represents a planview of the same. Fig-.6 represents aplan'view of the female mold and the parts by which it is operated, themachinerbeing represented as havingthe edge turnerand presser anditsguides removed and the male mold or last broken away. Fig.1? representsa plan view showing the relative positions of the moldsythe counterblank, and the presser at the beginning of the operationof turning outthe edge of the'counter. The" same reference characters indicate thesame parts in all the figures.

Referring to the drawings, theiframe. f

the machine is represented by 1, upon which are supported inclined bars2 connected at the front of the machine by a cross-piece 3. Supported bythe cross-piece 3 between the members 2 is a male mold or last 4: whichis fastened to a bolt 5 passing through ari apr erture 6 in thecross-piece 3, and is held against the latter by a spring 7 actingagainst the head 8 of the bolt. The female mold or mold proper consistsof two parts 9 and 10 secured to levers 11 and 12 which are plvoted upona cross head 13. The parts 9 and 10 of the mold are recessed at 14 and15 in their adjacent inner sides, these recesses together forming a moldwhich, when the members 9 and 10 are pressed toward each other, is ofthe shape of the counter or rear portion of a-shoe upper. The last ormale mold 4 is shaped at its end and sides so as to correspond with thecontour of the recesses 14 15 to cooperate with the female mold ingiving the shape to the upper. The sldes ofthe last are recessed, asshown b dotted lines at 16 and 17, so that the sides of the upper at theshank of the shoe may be brought inward nearer together than they are atthe heel portion.

-The'n1ale mold or last is normallv stationary and abuts againstthecross-piece 3 of the frame. The female mold is brought down to the lastand its members moved inward to bend the heel portion of the upperaround the last, by means of stiff spring fingers l9 and 20 whichproject beyond the ends of the levers 11 and 12 and are brought againstinclined wedge members 21 and 22. The reciprocating movement necessaryto carry the mold from the position shown in Fig. 6 to that in Figs. 3and is given by a cam 23 acting through a roll 24- upon a rod 25, whichlatter is connected to theknuckle 26 of'a toggle joint 27 28. Theabutment for the toggleis a plunger 29 which thrusts against a spring 30held by a bolt 31 and adjusting nut 32 which bears upper surfaces of themolds, and removed therefrom by a distance equal to the-thickness of theedge of the counter.

The presser or bender 37 is provided with ribs 40at its opposite sideswhich are contained in grooves in a frame'4l (see Fig. 4), which frameis mounted ina carriage 42 and carriesalso an elastic pad or cushion 43and a backing plate 44 which is pressed down upon the pad with more orless force by adjusting screws 45 so as to regulate the force with whichthe presser is caused to bear against the edges of the blank after ithas bent the same over. The carriage 42 has flanges46 which run in theguides 38 39 and are held therein by retaining strips 47. The

side members 48 of the carriage extend to a cross head 49 to which isconnected a link 50, thelatter being pivoted to a bell-crank lever 51having an arm 52 to which is pivoted-a connecting rod 53 having arolla54 which enters the groove of a positive cam 55.

As shown in Figs. 3, 5 and 6, the flange presser 37' has. one end 56formed as a rounded blunt end, and when not in operation, the presser isnormally held in front of the molds with its blunt end extending in thesamedirection as the last 4 and pointing toward the curved rear end ofthe latter and the bottom of the recess 14 15 in the female mold. It iscaused by its operating mechanism to reciprocate in the same directionas" the cross head 13 carrying themembers 9 10 of the mold is moved.Both the cams 55 and 23 are mounted upon the same shaft 57, which isdriven from a counter shaft 58 through a pinion 59 and gear 60. Thesecams bear such an angular relation to each other that when the machineis at rest, the members of the mold are separated from one another andthe presser is at its greatest distance in-front of the mold, leavingthe latter uncovered so as to receive an upper between them. Afterinsertion of an upper, this being accomplished through the space betweenthe sides 48 and the parts 4249 of the'carriage, the machine is set intomotion. The first part of the operation of the machine is effected bythe cam 23 and causes the members of the mold to be closed about thelast, shaping'the counter, portion of the upper and holding it inposition to be operated on by the presser. A long dwell of the cam 23,extending nearly through 180, as shown by dotted lines in Fig. 1, holdsthe molds while the presser is carried over them. Inits movement, thepresser advances toward the open end of the socket in the female mold,its wedge-shaped end- 5.6

The means for bending this it firmly againstthe same entering betweenthe ends of thefU -s'haped blank. As it progresses toward the rear endof the blank, it forces the edge thereof which projects from the molds"outward and lays it against the plane surface of the female mold: Theelastic pad 43 allows the 'presser to yield as it passes over the edgeof the upper, and at the same timepresses so as to give a permanent setto the flange 36, which is made by so laying over this edge.- Thepresser' remains in the positionshown in Fig.; 3, holding the overturnededge while the dwell from a-to Z of the cam 55. travels past the roll54. .The presser is then retracted,.- the femalemold withdrawn, and theupper is releasedso that-it -falls through an: opening 61 between. themembers2' of the frame. \Vhenthemembers 9 10 of the mold are withdrawn,they are separated from one another .by a pin 62 which is pressedagainst them between the pivots of the levers 1-1 and 12 by a spring 63.
